“Three weeks in and the bloating I'd just accepted as normal is gone. I didn't expect to feel the difference this clearly.”
“The only supplement I've actually kept taking. The refill shows up, the jar stays on my counter, done.”
“I love that they show the research instead of just making claims. First gut product I actually trust.”
Built by people
who needed it.
Tend started with a simple frustration: the supplement aisle was full of promises and short on proof. We set out to build the one daily formulation we’d actually take: rigorously studied, honestly labeled, and designed to last on your counter, not in a landfill.
Questions, answered.
Two capsules each morning, with or without food. Consistency matters more than timing. Pick a moment you’ll remember.
